CURLING-IRON HEATER,

SPECIFICATION forming part of Letters Patent No. 727,8 93,-da.te d May 12, 1903. Application filed November 23, 1901. Serial No. 83,453. (No model.)

To aZZ whom it may concern:

Be it known that we, MARY MYRTLE BUCK, of Machias, in the county of Cattaraugus and State of New York, and JOHN F. MALLINCK-' RODT, of Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Curling-Iron Heaters; and we do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in heaters for curling-irons, and more particularly to a device of this character which will. be coin-operated to permit the use of heated irons for a predetermined length of time, the object of the invention being to provide a curling-iron heater which can be placed in public places for the convenience of travelers or transients.

A further object is to provide acurling-iron' heater which will be small and compact, neat and attractive in appearance, comparatively cheap to manufacture, and of great convenience to the public at large. 7

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of, parts, as will be more fully hereinafter described, and pointed outin the claims.

In the accompanying drawings, Figure l is" a View illustrating our improvements. Fig. 2 is a side view with part of the casing removed. Fig. 3 is a plan view with the top and parts carried thereby removed. Figs. 4 and 5 are views of opposite ends of-the device with parts of the same removed; and Figs. 6, 7, and 8 are views of various details of con- 0 struction.

The working parts of our improved device are inclosed in a casing comprising top and bottom plates 1 2, front and rear plates 3, and end plates 4, all secured together by bolts,

screws, and rivets, as shown, forming a rectangular casing ornamented in any desired manner. In the casing, preferably near one end thereof, but arranged in alinement in the longitudinal center of the casing, are three tion 7 is provided for an electrical conductor 8, coiled around the same and inclosed in a covering of plaster-of-paris 9, openings being L provided in the top or cover 1 for the insertion of the curling-irons into the tubes, said openings being disposed eceentrically to the tubes to permit the irons tobe eifectually locked in the tubes, as will now be explained. The tubes 5 are each provided'between their ends with an opening to receive the short and flattened end of a counterweighted lockinglever 10, pivoted near its end between lugs 11 on the tube and whose'weight normally holds the inner end, which is flattened or has a flat plate secured thereto, against the curlingiron, thus forming, in effect, a Wedge, which will effectually prevent the removal of the iron until the weighted end of the locking-1ever is raised, but will not interfere with the downward movement of the iron, thus permitting its insertion after the levers have fallen l to their locking position. r r

- To raise the weighted ends of the locking levers 10 to a position to permit thewithdrawal of the'irons, we provide a series of fingers 12 below the same and projecting at right an 8o gles to a shaft 13, supported in standards 14,

secured to the base-plate, and p 'r'ovided at one end with a bifurcated arm 15, encompass: ing a push-rod 16, projecting up through the top plate 1 and providedat its upper endwith a button 17 and between its ends with a collar 18, adapted when the rod 16 is depressed to engage the arm 15, force itdownward, thus partiallyturning shaft 13 to raise the fingers 12 and elevate the weighted endsof the locking-levers 10 and permit the withdrawal and insertion of the irons just as long as the pushbar remains depressed. The downward move ment of push-rod 16 also forces the collar 18 against the inclined or cam face of a hook 19 93 on the upper end of a lever 20, having counterweighted arm 20, normally holding said hook against the collar, and this lever is secured on a shaft 21, supported in suitable hearings on the base-plate 2, thus moving the lever outward and partially turning the shaft 21, the collar 18 when moved to its lowest position catching below the hook 19 and being held in such position for a predetermined length of time, as will now be explained.

Supported in a frame 22 at one end of the casing is asuitable clockwork, operated by a spring 23 on an angular spindle 24, projecting through the end of the casing for the re ception of a key to wind the same. This clockwork mechanism is provided with the usual escapement-wheel 25 and with a timewheel 26, the latter made with a series of inclined teeth and notches 27 at the junction of said teeth. An elongated dog or catch 28, secured on shaft 21, is normally held in one of the notches 27 by the counterweighted arm 20; but when the shaft21 is partially turned by the collar 18 engaging the cam-face of hook 19 this dog 28 is moved out of a notch 27 and the escapem en t-wheel 25 started by an arm or pin 29 on the dog, thus starting the clockwork and turning the time-wheel 26 far enough to prevent the entrance of the dog into the notch, but presenting to the dog the inclined or cam edge of a tooth, which as the wheel turns moves the dog outward, thus slightly turning shaft 21 and moving lever 20 until just as the dog reaches the extremity of the tooth the hook 19 will be moved far enough to release the collar 18, permitting the push-rod 16 to be raised by a counterweighted lever 30, fulcrumed between its ends on an upright 31, secured to the base-plate 2, and engaging an adjustable collar 32 on the rod 16, which collar also serves as a stop, striking against the top plate 1 and limiting the upward movement of the rod. \Vhen the timewheel 26 turns far enough, this turning beiug timed to suit the length of time for which the irons are to be used, (five minutes being preferably allowed, and this time must elapse before the tooth will move along the dog,) the dog will springinto the next notch and stop the clock mechanism and hold it until the push-rod is again depressed.

To prevent the operation of push-rod 16, we provide a coin-operated mechanism comprising a vertical rod 33, having a weighted arm and pivoted at its lower end, as shown, and provided at its upper end with a notch or shoulder 34 to be moved below the collar 18 by the weighted arm 35 and preventing the downward movement of the push-rod. This rod 33 is provided at its upper end with an arm 36, extending at right angles thereto and carrying at its free end a basket or coin-receptacle 37, into which the coin is guided by a chute 3S, communicating with a slot in the top plate, and when the coin falls into the receptacle 37 it will overbalance the weighted arm 35 and draw the shoulder 3t frombeneath collar 18, thus permitting the rod 16 to be depressed.

On arm 36, near shoulder 34, a vertical fork 39 is located and has pivotally supported therein a trip 40 in the path of the collar 32. To this trip 40 an H-shaped bracket 11 is pivoted and carries in its bifurcated lower portion an arm 42, projecting into the receptacle and having a concave strip 43 to engage one edge of the coin when the latter rests in the basket, and it will be seen that when the rod 16 is depressed the collar 32 will strike trip 40,swingingiton its pivotand moving bracket 11 to thrust arm 42 forward, thus ejecting the coin from the receptacle and compelling the same to fall into a drawer 44, provided for the purpose, and hence freeing arm 36 from the weight of the coin and permitting the counterweight 35 to return the shoulder 3a as near as possible to its position to lock the collar 18. A weak spring 45 is secured to the rod 33 and bears at its free end against a pin 16 on arm 42 for returning the latter and the trip to their normal positions.

The operation of our improvements is as follows: \Vhen it is desired to use the curling-irons,a nickel or thepropercoin,as the case may be, is dropped into the chute 36 and falls into receptacle 37, thus overbalancing weight 35 and moving the shoulder 3% from beneath collar 18. The push-rod 16 is now depressed, moving the lever 20, through the medium of the cam-faced hook 19, to release the timewheel 26 and start the clockwork, as above described. This downward movement of the rod 16, through the medium of the collar 18, engaging the arm 15 on shaft 13, and hence by means of the fingers 12 raises the weighted locking-levers 10, permitting the withdrawal and use of the irons for a predetermined time (say five minutes) or, in other Words, until the time-wheel 26 shall have moved a distance of one tooth, as heretofore explained.

Instead of heating the tubes 5 by electricity we might heat them by gas, oil, or any other means, and hence we do not wish to be limited to the use of electricity, and various changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of our invention, and hence we would have it understood that we do not wish to limit ourselves to the precise details set forth, but consider ourselves at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of our invention.
